CULTIVATOR.

Specification of Letters Patent.

Patented May 15, 1906.

Application filed. August 1, 1905. Serial No. 272,226.

To all whom, it may concern.-

Be it known that I, EVANDER WILLIAMS, a citizen of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Cultivator, of which the following is a specification.

The invention relates to improvements in cultivators.

The object of the present invention is to im prove the construction of cultivators and to provide a simple and comparatively inexpensive one of great strength and durability having a plurality of cultivator blades or shovels and capable of ready adjustment for arranging such blades or shovels to provide either a straight or right or left hand cultivator.

With these and other objects in View the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of a cultivator constructed in accordance with this invention. Fig. 2 is a transverse sectional view. Fig. 3 is a detail sectional view taken longitudinally of the beam and illustrating the manner of adjustably securing the cross-head to the same. Fig. 4 is a detail perspective view of the cross-head. Fig. 5 is a similar view of the reversible fender.

Like numerals of reference designate corresponding parts in all the figures of the draw 111 's.

1 designates an adjustable cross head or bar centrally connected to a beam 2 by means of front and rear bolts 3 and 4 and extending from opposite sides of the beam and adapted to carry central and side cultivator blades or shovels 5 and 6. The adjustable cross-head preferably consists of a casting and is ribbed or flanged at opposite sides, as shown at 7, to secure the desired strength and lightness. It is provided at the central portion with front and rear projecting flanges 8 and 9, preferably segmental or substantially segmental and having curved series of perforations 10 and 11 for the reception of the front and rear bolts 3. and 4, which also pierce the beams. The bolts 3 and 4 and the curved series of and side standards 14 and 15.

face to fit against the lower face of the beam.

The cross-head is provided with central and side sockets 12 and 13, having openings which extend entirely through the cross-head and which receive the upper ends of central The standards are shown rounded in the accompanying drawings, and the sockets are cylindrical to receive the standards; but these parts may be made of any other desired shape, as will be readily understood. The standards are secured in the sockets by means of set-screws 16, located at the rear side of thecross-head and mounted in threaded perforations of the same. The set-screws pierce the rear walls of the sockets and clamp the standards securely to the cross-head. The lower ends of the standards are flattened to receive the cultivator blades or shovels, which may be of any preferred form and which are bolted to the standards in the ordinary manner. The cultivator is provided with a reversible fender consisting of a blade 17 and a shank or bar 18, adjustably connected at one end to the blade and detachably secured at the other end to the beam by a bolt 19 or other suitable fastening means. The bar or shank 18, which is arranged at an inclination, has its upper end 20 bent at an angle to the intermediate body portion of the shank or bar and fitted flat against one of the faces of the beam. The intermediate body portion of the shank or bar extends outwardly and rearwardly from the beam at an angle to the same, and its lower or rear end 21 is bent inwardly and is secured by a rivet 22 to the front portion 23 of the blade 17. The rear portion of the blade is substantially rectangular, and the front portion is tapered and bent at an angle to fit flat against the angularly-bent rear end 21 of the shank or bar. The rivet 22 forms a pivot for adjusting the blade on the shank or bar, and the blade is also provided at its front portion with a curved slot 24, arranged concentric with the pivot and receiving and clamping a bolt 25, which secures the blade in its adjustment. The rear or body portion of the blade is disposed at an angle to and diverges rearwardly from the beam, and it is designed to be arranged in advance of the front end of the cross-bar and is disposed substantially at right angles to the same when the proximate portion of the cross-bar extends forwardly from the beam at an acute angle to the same. The fender is adapted to be readily transferred from one side of the beam to the other, and the blade is adapted to be swung upwardly or downwardly on the rear end of the shank or bar to arrange it in the desired po- 'sition.

The cultivator-beam 2 has a suitable clevis at the front and is provided at the back with handles 26 of the ordinary construction.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.. The combination with a beam, of a cross-head extending laterally from opposite sides of the beam and provided at the central portion with front and rear projecting flanges having curved series of perforations, said crosshead being also provided with sockets, standards secured in the sockets and provided with cultivating blades or shovels, and front and rear fastening devices passing through front and rear perforations of the cross-head and'securing the same to the beam and permitting the cross-head to have a pivotal or rotary adjustment on the beam.

2. The combination with a beam, of a cross-head extending laterally from opposite sides of the beam and provided with longitudinal side flanges and having front and rear centrally arranged segmental flanges disposed horizontally and provided with curved series of perforations, said cross-head being also provided with sockets, front and rear fastening devices piercing the beam and arranged in front and rear perforations of the crosshead, and standards provided with blades or shovels and secured in the sockets of the cross-head.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

EVANDER WILLIAMS.
